With this release PyParticles become compatible with python 3.3, it need some other test but all mains functionalities works correctly. At the moment the main goal is to have an application that works either with python 2.7 and 3.3.
The second and very important point of this release are the testing, so I’ve finally written a pair of test procedures for comparing an analytical solution with the simulated solution.
For the moment the two tests are a falling object in a dragged fluid and the harmonic oscillator, and in both cases the result of the simulation is correct or, for be more precise, it follow the analytical solution with a very good approximation, so I can think that the procedures implemented in PyParticles are reliable.
In the following I report the absolute error for the harmonic oscillator (click for enlarge):
